Facial nerve aplasia is an extremely rare condition that is usually syndromic, namely, in Moebius syndrome. The occurrence of isolated agenesis of facial nerve is even rarer, with only few cases reported in the literature. We report a case of congenital facial paralysis due to facial nerve aplasia diagnosed on MRI, while no noticeable abnormality was detected on the temporal bone CT.

Le nœud iléo-sigmoïdien est une cause rare d'occlusion intestinale. Nous rapportons un cas de nœud iléo-sigmoïdien survenu chez une femme en post-partum. Le diagnostic a été évoqué sur les données du scanner et confirmé en peropératoire.

Digital Mammography is used as a screening tool to discover breast cancer at an early stage, the benefits and harms of this techniques is under scrutiny hence and Moroccan regulations governing radiation protection of patients have been strengthened, the need to investigate the dose received during screening mammography and the risk associated. This study is consisted of examining 126 mammography projections, for 63 women. All examinations were performed with a full digital mammography machine, technical and exposure parameters were recorded, statistical analysis was carried out using Microsoft Excel in order to calculate local DRLs and compare them with international standards. Cancer risk has been estimated using BEIR VII report methods. The mean glandular dose MGD was 1,09±0, 45 mGy and 1,26±0,74 mGy for craniocaudal (CC) and mediolateral oblique (MLO) respectively, DRLs were 1,34 for CC view and 1,36 for MLO view. Of the 100,000 women exposed, Lifetime Attributable Risk of cancer incidence has been found to be 0,76 for CC examination, 0.88 for MLO, and 1,64 for the full mammography protocol. Established local DRLs in this study are lower compared to that of United Kingdom and France and higher compared to that of Nigeria and Australia. A potential risk of radiation-induced carcinogenesis exists, and there is a need for optimization of screening mammography practices.

Carotid diaphragm usually can cause artery stenosis essentially affecting the internal carotid artery (ICA) beyond the bulb segment.  Patients are often middle aged and the onset of symptoms typically begins with syncopes leading to ischemic stroke.  More than 50 cases have been reported in which all lesions showed as stenosis located in the ICA, in this article, we report a rare common carotid artery (CCA) diaphragm revealed in a 59 year-old female suffering from transient syncopes. This is the third case reported in the literature.
